摘要
测定了尾式苯丙氨酸四苯基卟啉铁(Ⅲ)(Fe[Phe一Tpp]Cl)与锌粉、乙酸和咪唑组成的氧化模拟体系催化环氧化烯烃的吸氧动力学曲线,研究了不同轴向配体对体系催化活性的影响.实验结果表明,该体系催化环氧化各类烯烃的产物收率(Zn%)由高到低的顺序为:环己烯>1—癸烯>丙烯酸甲酯>烯两基丙酮,用吡啶代替咪唑可明显提高体系的最高吸氧速度.
This paper measures The oxygen wptake dynamical curue of ocxidation minetic system for alkenes epocidation and studies that the effect fi axial ligadns on the catalytic activity of the system,The system consists of Fe[phe-tpp]cl, The experimental results show that the epoxidation yields of the system diminish as follows :cyclohexene >1-decene>methyl projpenoicate>allylaceton and the highest uptake oxygen rate willbe incrased by substitutor pyridine for imidazole
